→ garyddt:是bond price 06/03 15:29
→ lovelymephy:感謝～我剛才也查了，但題目中似乎沒有明確說明@.@ 06/03 15:38
→ stranger19:X軸是bond price, Y軸是payoff 06/03 20:24
→ stranger19:所以是call option 06/03 20:25
推 speed8:call on coupon bond, put on par yield/swap rate 06/03 23:13
原題意是說 某人發表了一個statement :
A receiver swaption permits the holder to enter into a pay floating position
and is equivalent to a put option.
個人認為pay floating position 跟 as a put option都對，
但解答說receiver swaption is equivalent to a call option.
但receiver是當swap rate decrease時才valuable, 所以當預期 rate falling
時也會買reciever swaption啊。
題目也沒有說是equivalent to take put option against bond price
or interest rate.
有各位高手能協助解釋這題嗎？還是答案錯了？
